LibreYOLO combines those inference modules into one native file, disables the
otherwise wasted ImageNet backbone download, accepts a fixed same-sized tensor
batch with an all-false padding mask, and adds a tuple export wrapper. Module
names mirror upstream so the four official COCO state dictionaries load with
``strict=True`` and unchanged learned parameters.

Upstream ``models/transformer.py`` identifies its transformer as a modified
copy of ``torch.nn.Transformer``. PyTorch is distributed under BSD-3-Clause:
https://github.com/pytorch/pytorch. That inherited attribution is retained
here; LibreYOLO makes no separate derivation from another implementation.
